Which important information should a nurse teach a client diagnosed with primary open-angle glaucoma?

Teaching a client diagnosed with primary open-angle glaucoma about the risks associated with peripheral vision loss is essential for their safety and well-being. Individuals with this condition can experience a gradual reduction in peripheral vision, which can impair their ability to see objects or people approaching from the sides. This loss can significantly increase the risk of accidents while driving, making it important for the nurse to educate the client on the potential dangers involved.

Understanding the implications of peripheral vision loss can help clients make informed decisions about their activities, such as driving, where awareness of one's visual field is crucial. Addressing this issue can also encourage clients to seek regular eye examinations and adhere to prescribed treatments, thereby helping manage their condition more effectively.

The other options present misunderstandings about primary open-angle glaucoma. For instance, vision does not improve over time; rather, it typically declines without appropriate treatment. Additionally, the condition is not reversible, and while medication is the primary treatment method, it can also be managed through surgery in some cases, making it untrue that it can only be treated this way.
